Mini DCDC Buck Converter Module — compact, efficient stepdown power for electronics Why this module matters Converts a wide range of DC input voltages (5–15 V) to stable lower voltages, enabling reliable power for sensors, microcontrollers, and modules that require fixed lowvoltage rails. conversion efficiency (up to 92%) reduces heat and extends battery/runtime compared with linear regulators. Low output ripple (under 30 mV) and switching at up to 1.5 MHz (typically 1 MHz) deliver clean power for sensitive analog and digital circuits. Small, mini form factor fits tight spaces and integration into prototypes or final assemblies. Key specifications Input voltage: 5–15 V DC Available output voltages: 1.25 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V Maximum output current: 3 A Maximum conversion efficiency: 92% Output ripple: < 30 mV Switching frequency: typically 1 MHz, up to 1.5 MHz Performance and compatibility Designed to accept common DC sources in the 5–15 V range, making it suitable for 12 V systems, 5 V supplies, and other intermediate DC rails. Supports continuous loads up to 3 A; ideal where compact, efficient regulation is required. switching frequency enables smaller external components and reduces electromagnetic interference footprint when integrated sensibly. Practical use scenarios Embedded electronics: power 3.3 V microcontrollers, sensors, and peripherals from a single 12 V or 5–15 V supply. Automotive and mobile systems: step down vehicle 12 V rails to 5 V or 3.3 V for modules and data acquisition hardware. Batterypowered projects: improve energy efficiency and runtime when stepping down from multicell battery packs to logic voltages. Simple selection guidance Choose the module version with the required fixed output voltage (1.25 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, or 5 V). Observe the 3 A maximum output current rating and provision for heat dissipation in continuous load applications. Expect typical switching at 1 MHz with a maximum capability of 1.5 MHz and output ripple below 30 mV for stable operation. This mini buck converter delivers compact, efficient, and lownoise DC stepdown performance for a wide range of electronics projects and applications.
